DS34S101GN

Specialized ICS Overview

The DS34S101GN is a single-port TDM-over-Packet transport device compliant with IETF PWE3 SAToP, CESoPSN, TDMoIP, and HDLC standards. It transports one E1, T1, or serial stream transparently over IP, MPLS, or Ethernet networks. The component features an integrated 10/100 Ethernet MAC supporting MII/RMII/SSMII interfaces and glueless SDRAM buffer management. It operates from two clock signals for recovery and packet processing, utilizing a low-power 1.8V core and 3.3V I/O. The device supports up to 64 independently configurable bundles and handles network PDV, packet loss, and frequency changes via on-chip adaptive clock recovery.

Specialized ICS Feature Summary

• Supports SAToP, CESoPSN, TDMoIP (AAL1), HDLC, Unstructured, Structured, and Structured with CAS mapping methods.
• Includes an integrated 10/100 Ethernet MAC with selectable 32-bit, 16-bit, or SPI processor bus interfaces.
• Features on-chip TDM Clock Recovery Machines with algorithms handling network PDV, packet loss, and constant delay changes.
• Provides multiprotocol encapsulation support for IPv4, IPv6, UDP, RTP, L2TPv3, MPLS, and Metro Ethernet.

Specialized ICS Applications

• TDM Circuit Extension Over PSN
• Cellular Backhaul Over PSN
• Multiservice Over Unified PSN

Specialized ICS Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead-free status and RoHS compliance. Confirm package availability and moisture sensitivity levels prior to procurement. Ensure design compatibility with the 256 TECSBGA footprint and required external SDRAM components.

Specialized ICS Selection Notes

Select the DS34S101GN for applications requiring a single E1, T1, or serial stream transport. Compare against DS34S102GN, DS34S104GN, and DS34S108GN if multiple ports are needed. Verify that the 256-pin TECSBGA package meets board space constraints and that the operating temperature range of -40°C to +85°C suits the deployment environment.

Specialized ICS Part Context

The DS34S101GN belongs to the DS34S10x family of TDM-over-Packet devices manufactured by Analog Devices Inc./Maxim Integrated. This series includes variants with dual, quad, and octal port configurations. All models share similar architectural features but differ in the number of supported TDM streams and pin counts.

Specialized ICS Replacement Considerations

DS34S102GN+ (Dual Port), DS34S104GN+ (Quad Port). These parts share the same functional architecture but offer increased port density. Pinouts and register maps are compatible within the family, though physical pin assignments may vary slightly between port counts.
